Detachable extension rim for tractor wheels



srA'rEs FRED w. wLLIG, or GERVAIS, onEeoN.

To all whom t may concern.'

V Be it known that l, 'FRED W. YWILLIG, a citizen of the United States, residing at Gervais, in the county of Marion and State of Oregon, have invented certain new and useful improvements in Detachable VlnxtensionV Rims `for Tractor Wheels; doV declare the following to be a full, clear, and exact description of the invention, such as will enable others, skilled in the art to whichk it appertains to make and use the same. p

This invention relates to an auxiliary rim device to be used in connection with a con rentional structure et tractor Wheel and one object of the invention is to provide an attachment whichY can bel readily put in place and which will -be so constructed that it may be provided with cleats which will be mounted between v"side rings of-theattachment and will serve not .only as means for connecting the siderings o the attachment but further. serve as'extensions for the usual i comp anying drawings,

cleats which extend transversely of a tracf videdv with openings 5 so that lrivets or tor wheel.

Another object of the invention is yto so vconstruct this attachment that the inner ring ojt the device may be securedto an inwardly extending flange of the tractor wheel and spokes which are connected with the youter ring of the attachment secured to the hub o the tractor wheel by means of bolts which pass through a hub disk and the inner ends of the spokes and into the hub of the tractor.

Another object of the invention is to so construct this Vattachment that it may be 'formed otheavy sheet metal thus permit* ting it to be cheaply produced and at vthe same time permit of it being so constructed that it will be strong and durable.

Another object of the invention is to so construct this attachment that it will not tend to press down uponthe earth and form strips ol' relatively hard soil across a lield.-

Another object of theinvention is to so construct this attachment Athat the cross cleats may extend at an angle to the cleats which extend across the tractorwheel and thus permit of a very firm engagement with the ground.

This invention is illustrated in the acwherein:

Figure l is a perspective view showing the attachment applied to a tractor wheel ot a conventional construction.

Specification of Letters liatent.

'Patented May 2,1922.

Application led December 22, 1921. SerialNo. 524,171.

Figure 2 isa perspective view of one of the cleats which form part of the attachmem); ,Y v i vThis device is for use in connection with a conventional structure of tractor wheel and gin the present illustration has been shown applied to a tractor wheel W having a hub H, Vspokes which extend from the hub-to 'the rim of the wheel, and transversely extending.cleats C which extend diagonally across vtherim of the wheel and are't'ormedio angle iron as shown clearly in' Fig. 1. This rim is provided with inwardly extendinglianges so that the attachment can be readily connected with the Wheel as will be hereinafter brought out.

The attachment is provided with inner and outer Arings l and 2 whichare positioned in lspaced relation and held in the desired spaced relation by `cleats 3. These cleats are formed of heavy sheet metal, each of which is tormedfrom a re'ctangular'piece oit metal cut and bent to provide side arms Il which engage the rings l and 2 and are proother `suitable fasteners may be passed through the rings and side arms to ksecurely hold the cleats between the rings. The end portions of the outer portion of each vcleat extend beyond the side arms a and provide tongue extensions 7 and 8. The tongue eX- tensions which extend beyond the ring 2 extend in the saine plane with the body portions of the cleats but the tongue Vextensions 8 are bent asshown so that these tongues willimeet the ends of the cleatsor strips C which extend across the rim of the tractor wheel. ltwill thus be seen that when the auxiliary rim is l'put in place and secured by fastener bolts which will pass through the inner ring land inwardly extending flange of the wheel against which this ring lits, the ,cleats of the attachment will form continuations :of the cleats ot the main tractor wheel but will extend at substantially right angles to the cleats of the tractor` wheel and thus permit of a very firm grip being obtained upon the ground. In order to brace the outer ring and thus strengthen the attachment and further permit of the attachment being more securely connected with the tractor wheel, there has been provided spokes 9 which are secured to the outer ring by bolts or other suitable fasteners 10 and have their inner end portions extendin beneath a hub disk 11 so that securingv olts may he passed through the disk l1 and through the inner end portions of the spokes 9 and into the'lrub of the tractor Wheel. lt will thus he seenrthat this attachment Will he very firmly anchored to the huh and Arim portionsof the main tractor vWheel when in of a tractor wheel rim and a ring in spaced relation to the tiret mentioned ring, 4and cleat plats secured between the side rings and holding the rings in spaced relation and each having an outer end portion extending in `crossed y ating with cleats carriedhy therriin of a tractor wheel. 1

2. fr wheel attachment for Widening the rim of a tractor Wheel, said attachment including aV ring for fittingagainst the side of a tractor wheel rim and a ring in spaced relation vto the first mentioned ring'7 and cleat plates carried by said rings and each having an inner end portion extending hetxveen the rings and secured serving tohold the rings in spaced relation, the outer end portions ofthe cleat plates extending iii-crossed relation to the side rings and at one side extended for end to end contact with the cleatplates ofa tractor Wheel rim.

3. A Wheel attachment for Widening the rim of a tractor Wheel, said attachment inlient for end to end contact extending diagonally across a tractor Wheel relation to the rings for co-oper-v to the rings and Vcluding e ring for fitting against the`side of a tractor Wheel rim and a ring in spaced relation to 'the first mentioned ring, and cleatV plates carried by said. rings and each having an inne;1 end portion extendingbetween the rings and provided with side arms vsecured against the sides of said'rings and .an outer .end portionl extending 1n crossed relation to the ringsrWith the portion extending in crossed relation to theinner ring with cleat plates rim.

fl. fi. nf'heel attachment comprising spaced ide rings, cleats secured to and extending s between the side rings in spaced relation and having enter end portions extendmgbeyond the rings?. a hub plate, spokes connected With" one of said rings, and fasteners passing through the vhub plate and' spokes forsecuring the spokes and hub plate against the hub positioned to .one side thereof.

5. A Wheel attachment comprising spaced side 'rings7 cleats'between the side rings secured against the inner side faces thereof and of a tractor wheel havin@ the attachment Vextending outwardly beyond the rings and havingV their outer end portions extending in overlapped relation to the sid at one side bent to extend for end to end contact with cleat strips extending diago-` nallyracross the rim of a tractor wheel,spokes connected with the outer side ring7 and a'V rings and Y huh-engaging disk connected with the inner ends of said spokes. l
